实现能够选择文件夹

  大家都用过C#里的文件打开/保存对话框吧?方便明快且易上手.但是可惜的是,C#居然没提供同样的文件夹选择框,很多人通过P/I invoke使用了系统的一些函数来实现对话框,那是相当地不方便啊~~其实,C#的FolderNameEditor类在某种程度上就实现了文件夹选择框的功能,只不过没有完全包装出来.呵呵,今天就给读者放出一个使用C#自己的类实现的对话框,使用起来就跟OpenFileDialog一样简单易用.
 
//给文件夹选择框类起名叫OpenFolderDialog,类设计如下: public class OpenFolderDialog : FolderNameEditor, IDisposable { FolderNameEditor.FolderBrowser fDialog = new FolderNameEditor.FolderBrowser(); public OpenFolderDialog() { } public DialogResult ShowDialog() { return ShowDialog("Select a folder:"); } public DialogResult ShowDialog(string description) { fDialog.Description = description; return fDialog.ShowDialog(); } public string Path { get { return fDialog.DirectoryPath; } } public void Dispose() { fDialog.Dispose(); } } //使用实例: private void selectFolderButton_Click(object sender, EventArgs e) { using (OpenFolderDialog openFolderDlg = new OpenFolderDialog()) { if (openFolderDlg.ShowDialog() == DialogResult.OK) { this.outFolderTextBox.Text = openFolderDlg.Path; } } } //下面是对照的OpenFolderDialog使用实例,对照一下,是不是很相似? private void selectFileButton_Click(object sender, EventArgs e) { using (OpenFileDialog openDlg = new OpenFileDialog()) { openDlg.Filter = @"All text Files(*.txt)|*.txt"; openDlg.Multiselect = false; openDlg.RestoreDirectory = true; openDlg.FilterIndex = 1; if (openDlg.ShowDialog() == DialogResult.OK) { this.filePathTextBox.Text = openDlg.FileName; } } }
